Adaptação transcultural do questionário VEINES/QOL-SYM: avaliação da qualidade de vida e sintomas na doença venosa crônica Transcultural adaptation of VEINES/QOL-Sym questionnaire: evaluation of quality of life and symptoms in chronic venous disease
Abstract
OBJETIVO: Adaptar transculturalmente e analisar as propriedades clinimétricas do VEINES-QOL⁄Sym, um questionário específico para avaliar a qualidade de vida e os sintomas na doença venosa crônica. MÉTODOS: O VEINES-QOL⁄Sym foi adaptado segundo metodologia recomendada e aplicado em 74 indivíduos (53,7±12,3 anos) com doença venosa crônica, assistidos ambulatorialmente. RESULTADOS: Os resultados evidenciaram boa consistência interna do VEINES-QOL (alfa de Cronbach -α=0,88) e do VEINES/Sym (α=0,84). A confiabilidade inter e intra-examinadores avaliadas pelo coeficiente de correlação intraclasse variou de 0,95-0,98 para o VEINES-QOL e de 0,76-0,79 para o VEINES/Sym. O coeficiente de correlação intraclasse foi calculado para cada item e alguns apresentaram valores abaixo do esperado merecendo revisão. As correlações com SF-36 foram significativas (pOBJECTIVE: To adapt cross-culturally and to analyze the clinimetric properties of the VEINES-QOL⁄Sym, which is a specific questionnaire to evaluate the quality of life and symptoms in patients with chronic venous disease. METHODS: The VEINES-QOL⁄Sym was adapted according to the recommended methodology and administered to 74 subjects (53,7±12,3 years-old) with chronic venous disease, who were assisted at the outpatient clinic. RESULTS: The results showed a good internal consistency for VEINES-QOL (Cronbach's alpha (α) = 0,88) and VEINES/Sym (α=0,84). The inter and intra-rater reliability evaluated by the Intraclass Correlation Coefficient ranged from 0,95-0,98 for VEINES-QOL and 0,76-0,79 for the VEINES/Sym. The intraclass correlation coefficient was calculated for each item and some of them showed values lower than the expected, deserving a revision. The correlations with SF-36 were significant (p<0.001); however, of moderate magnitude. Only the VEINES-QOL was capable to distinguish the subjects in two groups, according to the severity of chronic venous disease (p=0.02). CONCLUSION: The VEINES-QOL/Sym, Brazil-Portuguese version has presented good clinimetric properties and has shown to be applicable to the population
